update still overheating any other ideas

[cookies2shoes]

ok so i jacked the back up and bled the system like 3 times,ive replaced evrything including the radiator and cluster it still goes up to almost 3/4 i hooked my heater core back up it will only go back down if i have the heat cranked up on defrost.very frustrating because i live in 100 plus degree temps my ac works great but ive dumped so much time and money into this one.i replaced the temp sensor before i moved down here and had the code cleared not sure what to do next.could the damage sustained from the previous owner been enough to cause a restriction in the head or rear cooling pipes/hoses.thanks any suggestions would be helpful. 2.8 v6 b5

Your post is confusing but i'll try. I didnt read your first post so i dont know what's going on. How is your fan clutch? Do your fans come on? When the car sits and idles does it overheat? goes all the way up to red or what? When was the last time thermostat was replaced and does it leak any coolant out?

I need more from you, what does the car do act and how long does it take to overheat?

does anyone know how fast is the main cooling fan supposed to spin?(in order to assist in cooling of engine.mine seems to spin fairly slow.does anyone know how this system works(viscus clutch=dont' know if i spelled that correctly.anyways i have to date replaced everything(t-belt/h20 pump/tstat/radiator/serp belt/tensioners/idler roller/temp sensor on backside of engine/g-12/i have bled the cooling system 3 times and w/rear of car up in air.even gauge cluster,i am stumped,i will note that previous owner ran regular antifreeze,heater core is bypassed/although i've tried to no avail w/heater core hooked up but w/ small leak.i will also mention that at normal driving and down here in palm springs its been 100-110 degrees the temp gauge will go to a little past the first big mark after straight up and down.in the evening or on the freeway especially when its cooler like 90 the gauge at like 45-50 will go down to normal temp straight up and then creep back to the next big mark on gauge.this sounds like to me a cooling fan issue,only after i replaced everything else.also when i turn of the car i here a weird hiss sound for about ten seconds,it sounds like its coming from one of the ac lines,although my ac works fine and the small ac fan comes on fine.can anyone think of anything?

Dude! I can't even finish reading your post, because of the horrible run on sentences and lack of punctuation. Slow down and think about what you are going to say one sentence at a time!
